  • Are alkyl diol dibenzoate compounds effective in plasticizing PVC?
  • The effectiveness of the tested alkyl diol dibenzoate compounds was assessed as a combination of the various reported material properties. Of the four compounds tested in this study, 1,3-PrDB, 1,5-PDB, and 1,6-HDB (Figure 2) proved to be as effective in plasticizing PVC as the widely- and commercially-used plasticizer DEHP in blends at 40 phr.
  • Is dibenzoate plasticizer effective in poly (vinyl chloride)?
  • 4.1. Dibenzoate Plasticizer Effectiveness in Poly (Vinyl Chloride) The effectiveness of the tested alkyl diol dibenzoate compounds was assessed as a combination of the various reported material properties.
  • Is 1,5-pentanediol dibenzoate a PVC plasticizer?
  • In a previous study, 1,5-pentanediol dibenzoate (1,5-PDB, see Figure 2) has been proposed and tested as a PVC plasticizer, since the only difference between 1,5-PDB and DEGDB lies within the diol linker part: the oxygen atom of the ether bond in DEGDB is replaced with a carbon atom in 1,5-PDB.
  • Are diol dibenzoates safe?
  • The results were compared to blends of PVC/di (2-ethylhexyl) phthalate (DEHP), the most commonly used commercial plasticizer. DEHP has come under scrutiny, due to its suspected endocrine-disrupting behaviour, and the proposed diol dibenzoates have previously been shown to have the potential to be green, safe candidates for DEHP replacement.
  • Could diol dibenzoate replace phthalates?
  • Further, the proposed diol dibenzoate compounds could be good green candidates to replace phthalates, given previous work that identified their rapid biodegradation by soil bacteria [21, 24, 30].
  • What is a dibenzoate plasticizer?
  • While several commercial dibenzoate plasticizers, such as diethylene glycol dibenzoate (DEGDB) and dipropylene glycol dibenzoate (DPGDB; see Figure 2), are sold commercially [18, 19], these compounds generally contain ether linkages in their central linker connecting the two benzoate moieties.
